Polygraf AI Reviews

Well it appears you need to bend the knee to get most features. It would have felt more "normal" if one could gain access to most features and just have less credits to do so because whatever this is just doesn't feel right. . . Anyway .

I am finding some bugs in the system. Key tools like Stealth AI, Content Enhance, Humanized TextDetector, and Copyright Detector are not included in the lifetime deal.

I have tested the AI-detected component and tried to humanize it using the options available on the platform. However, when I tested that content on another platform, it showed as 100% AI-generated content, whereas it was the same on this platform. I think AI detection and humanizing content are still grey areas, and it's very hard to achieve 100% accurate results for this.

Polygraf AI fits seamlessly into our workflow, making it the final piece of the puzzle.

We already have several AI apps with features similar to Polygraf, but only as an extra function—not as the core feature. It's great to see an app that focuses on data provenance instead of just offering it as a bonus feature. This is exactly what we’re looking for, and we like it! 🏅💯🚀

For our initial test, I used a workflow combining AI Detector, AI Highlighter, and AI Humanizer.

A blog I wrote in 2022 without using AI received a Human Score of 99.86% (perfect).

A more recent blog I created in 2025 with AI scored 73.5% for AI Generated content (poor).

After humanizing it with Polygraf, the AI score dropped to 34.6% (much better).

Although it’s still slightly above the 30% AI detection threshold, this decrease of almost half the score is a significant improvement. As with all AI platforms, manual tweaking is always expected. 👍

Cognitive Flow Index also slightly improved from 67 to 71.

The "Compare" feature is very helpful. "Grammar enhanced" writing was detected by Polygraf in the comparison - detecting what percentage of the article was improved from the original.

The Writing Analysis Tool is a great addition which functions similar to Grammarly. Comparing the 2 versions (before & after) on the Writing Analysis tool shows minor improvements (around 3%) in the scores on readability, Syntactic Tree Depth, Vocabulary Richness, and Cognitive Flow Index.

I got the LTD and the 150K tokens seems more than enough for light casual users. But for the heavy daily users, they might need the annual plan. Tokens can get consumed quickly if you use all the tools on a single project like the AI Detector, AI Highlighter, AI Humanizer, Comparison, and Writing Analysis tools. Fortunately, Yagub mentioned that they are optimizing token spending which can reduce our token costs by 25-35% in certain features. 👍

I hope they can add a PAYGO option for casual or seasonal users whose needs vary depending on project load.

The History feature is still in Beta, so make sure to save your work locally in a Word document or something similar. I hope the team can prioritize this.

The only letdown for me was the absence of the Copyright Detector in the LTD. I hope they consider including this feature in the LTD—even with slightly higher token costs. It would make Sumolings very happy! 🙏😊

To wrap up, we recommend Polygraf to copywriters, marketers, students, and educators as we believe it has the potential to become a top player in the AI space quickly, especially since the founder, Yagub, is an award-winning tech entrepreneur. 🏆✨

I wanted to test this tool out; this is what I found:

1. Credits go very fast—1000 words = 4000 credits.
2. I compared AI content, human content, and strange, It said the AI content was 50% AI-written, while the human content was 30% AI-written, which seems quite strange. I also tested free alternatives like QuillBot and ZeroGPT, which both showed the AI content as 99% AI-written, while my human content was labeled as 100% human.

It seems the free alternatives are more accurate. That’s why I’m refunding—what’s the point if I can do detection for free elsewhere? Also, when I logged in for the first time, many features just said "Upgrade." Essentially, all you get are 3-4 small features like AI detection—that’s it.
